axle question

Good video.
It looked like that wheel has a four bolt sprocket. My Honda 400 has a four bolt sprocket. It might be an XS400 wheel.
That little bolt holds the flexible plate in the end of the swing arm and gives the axle adjuster something to push against. The part that is held in is kinda tee shaped.
If you look at the parts fiche at boats.net or babbittsonline or most any parts seller you will see the parts.
If who ever put the wheel on didn't grease the axle, then it often gets rusted into the wheel. Soaking it as good as you can with a good penetrating lube, like PB Blaster will help. A good pounding with your BFH might be what it takes.
You may need to replace the axle afterwards but you will get it out.

That spacer with the flange goes right against the inner bearing race, the flange is a dust cover that keeps most of the crud away from the bearing. More to protect the seal on the bearing than the actual bearing.
It looks like you have gained a bit. Spray the penetrating lube in by the axle and around the spacer.
You should be able to get it to slide out with some persuasion from the BFH.
I like the video part of your posts. Very helpful, better than pics.
Like the bike stand, very nice to have if you don't have the center stand on the bike.

An idea. It doesn't look like you have the standard swingarm, so this might work. 1. Remove chain. 2. Loosen and remove top bolt on axle adjuster assembly. 3. Slide wheel off and then pull axle out.

Thinking about it this morning, forgot to check to see if you have disc brake, sure enough you do. The idea may still work but you would have to unbolt the caliper retaining rod and there would have to be enough slack in the brake line to let you pull the wheel off.

The first few years 70-73 they used a closed loop swingarm. In 74 when they did many frame mods the changed to an open ended swing arm. On the later models, 81, they went back to a closed loop.
I went and snagged pics from boats.net.
#1 is the 70-73, #2 is 74 to 80, #3 is 81 up.
In pic #2 part 10 is the tee shaped block held in by bolt 11. You can remove bolt 11 and pull the axle, adjusters and the wheel together. On your disc brake you can pull the caliper off the bracket by removing the bolt at the bottom of the caliper. This way it won't disturb the brake, you leave the line hooked up. Just hang it up out of the way. On the bracket you will need to unhook one end of the strut.
This will get the wheel out but you will still have the axle stuck. It will give you more room to work, and you can get the wheel up on the bench where it's easier to work with.
